There is no need to have configuration files direbtly set the
BR2_PACKAGE_HOST_ELF2FLT option. The need for the elf2flt utility is
automatically determined by gcc build in package/gcc/gcc.mk according to
the BR2_BINFMT_FLAT option.
Accordingly, we can remove the file package/elf2flt/Config.in.host to
get rid of the BR2_PACKAGE_HOST_ELF2FLT option. BR2_STRIP_strip
dependency on this option is replaced with a dependency on
BR2_BINFMT_ELF.
To stay consistent with the fact that elf2flt supports only the arm, sh,
sparc, xtensa and riscv-64 architectures, a dependency on these
architectures is added to the BR2_BINFMT_FLAT option in arch/Config.in.
Board configuration files setting the BR2_PACKAGE_HOST_ELF2FLT option
are also updated.

The Linux environment for all boards using the Canaan Kendryte K210 SoC
can be built with the same process, using configurations that differ
only by the device tree used for the build. This patch add the
shared configurations, rootfs overlay and scripts used for all
K210-based boards.
Since the K210 SoC only has 8 MB of SRAM, a special busybox
configuration and rootfs overlay are added to save memory at runtime:
* For configurations using direct kernel boot (no boot loader), the
default busybox configuration busybox-minimal.config is modified
using the fragment file board/canaan/k210-soc/busybox-tiny.config.
This reduces the size of the busybox executable to save memory when
executing shell commands.
* Busybox init system is not used and a special init scripts is provided
using the rootfs_overlay root file system overlay. This init script
simply mounts devtmpfs, /proc and /sys, and exec an interactive shell
after printing a logo. This avoids (1) boot failures due to large
memory allocations by the regular busybox init system (these
allocations fail on the K210 for lack of enough memory) and avoids
(2) keeping the init process sleeping in the background (wasted
memory).
The board/canaan/k210-soc/busybox-tiny.config and the rootfs overlay
files in board/canaan/k210-soc/rootfs_overlay are used for all Canaan
K210 SoC based boards.
For board configurations booting using the U-Boot boot loader, a common
set of linux kernel configuration parameters is provided by the file
board/canaan/k210-soc/linux-sdcard.config. In addition, the post build
script board/canaan/k210-soc/post-build.sh file and U-Boot image
generation configuration file board/canaan/k210-soc/genimage.cfg are
provided. The post-build script creates a generic "k210.dtb" symlink to
the compiled device tree file for the target board. This symlink is used
by the genimage.cfg configuration, making this file common for all
boards.

Add two buildroot configuration files to build a minimal Linux
environment for the Sipeed MAIX Bit board. The configurations are:
* sipeed_maix_bit_defconfig: Build a bootable kernel image with an
embedded initramfs root file system. The image built can be flashed to
the board as is and does not require a boot loader. This configuration
uses the tiny busybox configuration defined in
board/canaan/k210-soc/busybox-tiny.config.
* sipeed_maix_bit_sdcard_defconfig: Build a kernel image with a root
file system on the SD card and using U-Boot as the boot loader. This
uses the default busybox minimal configuration.
Both configurations also enable the python-kflash and pyserial-miniterm
host tools for flashing image files to the board and opening a terminal
console.
The readme.txt file documents how to build and boot the Sipeed MAIX-Bit
board with these configurations.

+Sipeed MAIX-Bit Board
+=====================
+
+The Sipeed MAXI-Bit board is a dual-core RISC-V 64-bits board based on the
+Canaan Kendryte K210 SoC.
+
+Prerequisite
+------------
+
+In order to use the kflash utility to program this board, the user must have
+access to the board USB serial device file. The simplest way to do this is to
+add your user to the same group as this device file. Assume the device file is
+/dev/ttyUSB0, first identify the device group name. In most cases, it is
+either "dialout" or "uucp". Also verify that read-write access is enabled for
+the group:
+
+```
+$ ls -l /dev/ttyUSB0
+crw-rw---- 1 root dialout 188, 0 May 26 13:48 /dev/ttyUSB0
+```
+
+Then add yourself to that group (dialout in this example):
+
+```
+$ sudo usermod -a -G dialout $(whoami)
+```
+
+To enable the above, it is sometimes necessary to logout and login again.
+
+Buildroot Configuration
+-----------------------
+
+Two buildroot configuration files are provided:
+
+(1) Direct Linux Kernel Boot
+
+This is defined by the sipeed_maix_bit_defconfig configuration. This
+configuration allows building a bootable kernel image with a built-in initramfs
+root file system (the board SD card is not used). The built kernel image can be
+flashed directly to the board ROM for direct booting. No boot loader is
+required.
+
+(2) U-Boot SD-Card Boot
+
+The sipeed_maix_bit_sdcard_defconfig configuration allows building a kernel
+image with the root file system on the board SD card. U-Boot is used as the
+boot loader.
+
+Both configuration files will also compile and install the kflash and
+pyserial-miniterm host utilities to program bootable image files to the board
+and open a serial terminal console.
+
+Direct Linux Kernel Boot
+-------------------------
+
+Using the sipeed_maix_bit_defconfig configuration, the bootable kernel binary
+image is built as follows.
+
+```
+$ make sipeed_maix_bit_defconfig
+$ make
+```
+
+The bootable binary image is the output/images/loader.bin file. This image file
+can be written to the board boot ROM using the kflash utility.
+
+```
+$ output/host/bin/kflash -b 1500000 -p /dev/ttyUSB0 -t output/images/loader.bin
+```
+
+Once the kernel image file is fully programmed, a terminal console is open and
+the board can be rebooted by pressing the reset button on the board (if it does
+not reboot automatically).
+
+The output will be similar to the following.

+
+To open a terminal console without re-flashing the board, the pyserial-miniterm
+host tool can be used.
+
+```
+$ output/host/bin/pyserial-miniterm --raw --eol=LF /dev/ttyUSB0 115200
+```
+
+The options "--raw" and "--eol=LF" are added here to avoid a double carriage
+return each time a command is entered.
+
+
+U-Boot SD-Card Boot
+-------------------
+
+The build procedure is similar to the direct Linux kernel boot case.
+
+```
+$ make sipeed_maix_bit_sdcard_defconfig
+$ make
+```
+
+The build process will generate two files under the output/images directory.
+
+* sdcard.img: The image file for the SD card filesystem. This image has 2
+ partitions. The first partition is a vfat partition containing the kernel
+ uImage and the board device tree binary. The second partition is the root
+ filesystem with busybox installed. The second partition is formatted using
+ ext2 (rev1).
+
+* uboot.bin: U-Boot bootable binary to load and boot the kernel from the SD
+ card.
+
+The SD card can be prepared by writing the sdcard.img file, as follows.
+
+```
+$ sudo dd if=output/images/sdcard.img of=/dev/sdX bs=1M
+$ sync
+$ eject /dev/sdX
+```
+
+Where /dev/sdX is the device file name of the SD card. Once completed, the SD
+card can be inserted into the board and the U-Boot binary image written to the
+board boot flash using the kflash utility.
+
+```
+$ output/host/bin/kflash -b 1500000 -p /dev/ttyUSB0 -t output/images/u-boot.bin
+```
+
+The above command will program U-Boot image to the board boot ROM and open a
+terminal console once the u-boot.bin file is fully programmed. Reboot into the
+newly programmed environment by pressing the board reset button.
+
+The output will be similar to the following.
+
+```

+
+Of note is that the kernel mounts the SD card as read-only by default to avoid
+corruptions of the ext2 root file system when the board is powered down. This
+is recommended as this board does not support clean shutdown or halt.
+
+Similarly to the initramfs build case, a console can be open without

Add two buildroot configuration files to build a minimal Linux
environment for the Sipeed MAIXDUINO board. The configurations are:
* sipeed_maixduino_defconfig: Build a bootable kernel image with an
embedded initramfs root file system. The image built can be flashed to
the board as is and does not require a boot loader. This configuration
uses the tiny busybox configuration defined in
board/canaan/k210-soc/busybox-tiny.config.
* sipeed_maixduino_sdcard_defconfig: Build a kernel image with a root
file system on the SD card and using U-Boot as the boot loader. This
uses the default busybox minimal configuration.
Both configurations also enable the kflash and pyserial-miniterm host
tools for flashing image files to the board and opening a terminal
console.
The readme.txt file documents how to build and boot the Sipeed MAIXDUINO
board with these configurations.

+Sipeed MAIXDUINO Board
+======================
+
+The Sipeed MAIXDUINO board is a dual-core RISC-V 64-bits board based on the
+Canaan Kendryte K210 SoC. This board has the same form factor as the Arduino
+UNO board.
+
+Prerequisite
+------------
+
+In order to use the kflash utility to program this board, the user must have
+access to the board USB serial device file. The simplest way to do this is to
+add your user to the same group as this device file. Assume the device file is
+/dev/ttyUSB0, first identify the device group name. In most cases, it is
+either "dialout" or "uucp". Also verify that read-write access is enabled for
+the group:
+
+```
+$ ls -l /dev/ttyUSB0
+crw-rw---- 1 root dialout 188, 0 May 26 13:48 /dev/ttyUSB0
+```
+
+Then add yourself to that group (dialout in this example):
+
+```
+$ sudo usermod -a -G dialout $(whoami)
+```
+
+To enable the above, it is sometimes necessary to logout and login again.
+
+Buildroot Configuration
+-----------------------
+
+Two buildroot configurations are provided:
+
+(1) Direct Linux Kernel Boot
+
+This is defined by the sipeed_maixduino_defconfig configuration. This
+configuration allows building a bootable kernel image with a built-in initramfs
+root file system (the board SD card is not used). The built kernel image can be
+flashed directly to the board ROM for direct booting. No boot loader is
+required.
+
+(2) U-Boot SD-Card Boot
+
+The sipeed_maixduino_sdcard_defconfig configuration allows building a kernel
+image with the root file system on the board SD card. U-Boot is used as the
+boot loader.
+
+Note: U-Boot does not natively support the Sipeed MAIXDUINO board. However, the
+board and device tree differences with the Sipeed MAIX-bit board are small
+enough for U-Boot to work.
+
+Both configuration files will also compile and install the kflash and
+pyserial-miniterm host utilities to program bootable image files to the board
+and open a serial terminal console.
+
+Direct Linux Kernel Boot
+------------------------
+
+Using the sipeed_maixduino_defconfig configuration, the bootable kernel binary
+image is built as follows.
+
+```
+$ make sipeed_maixduino_defconfig
+$ make
+```
+
+The bootable binary image is the output/images/loader.bin file. This image file
+can be written to the board boot flash using the kflash utility.
+
+```
+$ output/host/bin/kflash -b 1500000 -p /dev/ttyUSB0 -t output/images/loader.bin
+```
+
+Once the kernel image file is fully programmed, a terminal console is open and
+the board can be rebooted by pressing the reset button on the board (if it does
+not reboot automatically).
+
+The output will be similar to the following.
+

+
+To open a terminal console without re-flashing the board, the pyserial-miniterm
+host tool can be used.
+
+```
+$ output/host/bin/pyserial-miniterm --raw --eol=LF /dev/ttyUSB0 115200
+```
+
+The options "--raw" and "--eol=LF" are added here to avoid a double carriage
+return each time a command is entered.
+
+
+U-Boot SD-Card Boot
+-------------------
+
+The build procedure is similar to the built-in initramfs case.
+
+```
+$ make sipeed_maixduino_sdcard_defconfig
+$ make
+```
+
+The build process will generate two files under the output/images directory.
+
+* sdcard.img: The image file for the SD card filesystem. This image has 2
+ partitions. The first partition is a vfat partition containing the kernel
+ uImage and the board device tree binary. The second partition is the root
+ filesystem with busybox installed. The second partition is formatted using
+ ext2 (rev1).
+
+* uboot.bin: U-Boot bootable binary to load and boot the kernel from the SD
+ card.
+
+The SD card can be prepared by writing the sdcard.img file, as follows.
+
+```
+$ sudo dd if=output/images/sdcard.img of=/dev/sdX bs=1M
+$ sync
+$ eject /dev/sdX
+```
+
+Where /dev/sdX is the device file name of the SD card. Once completed, the SD
+card can be inserted into the board and the U-Boot binary image written to the
+board boot flash using the kflash utility.
+
+```
+$ output/host/bin/kflash -b 1500000 -p /dev/ttyUSB0 -t output/images/u-boot.bin
+```
+
+The above command will program U-Boot image to the board boot ROM and open a
+terminal console once the u-boot.bin file is fully programmed. Reboot into the
+newly programmed environment by pressing the board reset button.
+
+The output will be similar to the following.

+
+Of note is that the kernel mounts the SD card as read-only by default to avoid
+corruptions of the ext2 root file system when the board is powered down. This
+is recommended as this board does not support clean shutdown or halt.
+
+Similarly to the initramfs build case, a console can be open without
+re-flashing the board using the host tool pyserial-miniterm.

Add two buildroot configuration files to build a minimal Linux
environment for the Sipeed MAIX-Dock board. The configurations are:
* sipeed_maix_dock_defconfig: Build a bootable kernel image with an
embedded initramfs root file system. The image built can be flashed to
the board as is and does not require a boot loader. This configuration
uses the tiny busybox configuration defined in
board/canaan/k210-soc/busybox-tiny.config.
* sipeed_maix_dock_sdcard_defconfig: Build a kernel image with a root
file system on the SD card and using U-Boot as the boot loader. This
uses the default busybox minimal configuration.
Both configurations also enable the kflash and pyserial-miniterm host
tools for flashing image files to the board and opening a terminal
console.
The readme.txt file documents how to build and boot the Sipeed
MAIX-Dock board with these configurations.

+Sipeed MAIX-Dock Board
+======================
+
+The Sipeed MAXI-Dock board is a dual-core RISC-V 64-bits board based on the
+Canaan Kendryte K210 SoC.
+
+Prerequisite
+------------
+
+In order to use the kflash utility to program this board, the user must have
+access to the board USB serial device file. The simplest way to do this is to
+add your user to the same group as this device file. Assume the device file is
+/dev/ttyUSB0, first identify the device group name. In most cases, it is
+either "dialout" or "uucp". Also verify that read-write access is enabled for
+the group:
+
+```
+$ ls -l /dev/ttyUSB0
+crw-rw---- 1 root dialout 188, 0 May 26 13:48 /dev/ttyUSB0
+```
+
+Then add yourself to that group (dialout in this example):
+
+```
+$ sudo usermod -a -G dialout $(whoami)
+```
+
+To enable the above, it is sometimes necessary to logout and login again.
+
+Buildroot Configuration
+-----------------------
+
+Two buildroot configuration files are provided:
+
+(1) Direct Linux Kernel Boot
+
+This is defined by the sipeed_maix_dock_defconfig configuration. This
+configuration allows building a bootable kernel image with a built-in initramfs
+root file system (the board SD card is not used). The built kernel image can be
+flashed directly to the board ROM for direct booting. No boot loader is
+required.
+
+(2) U-Boot SD-Card Boot
+
+The sipeed_maix_dock_sdcard_defconfig configuration allows building a kernel
+image with the root file system on the board SD card. U-Boot is used as the
+boot loader.
+
+Note: U-Boot does not natively support the Sipeed MAIX-Dock board. However, the
+board and device tree differences with the Sipeed MAIX-Bit board are small
+enough for U-Boot to work.
+
+Both configuration files will also compile the pyserial-miniterm host tool open
+a serial terminal console for the board.
+
+Direct Linux Kernel Boot
+-------------------------
+
+Using the sipeed_maix_dock_defconfig configuration, the bootable kernel binary
+image is built as follows.
+
+```
+$ make sipeed_maix_dock_defconfig
+$ make
+```
+
+Both configuration files will also compile and install the kflash and
+pyserial-miniterm host utilities to program bootable image files to the board
+and open a serial terminal console.
+
+```
+$ output/host/bin/kflash -b 1500000 -p /dev/ttyUSB0 -t output/images/loader.bin
+```
+
+Once the kernel image file is fully programmed, a terminal console is open and
+the board can be rebooted by pressing the reset button on the board (if it does
+not reboot automatically).
+
+The output will be similar to the following.
+

+
+To open a terminal console without re-flashing the board, the pyserial-miniterm
+host tool can be used.
+
+```
+$ output/host/bin/pyserial-miniterm --raw --eol=LF /dev/ttyUSB0 115200
+```
+
+The options "--raw" and "--eol=LF" are added here to avoid a double carriage
+return each time a command is entered.
+
+
+U-Boot SD-Card Boot
+-------------------
+
+The build procedure is similar to the built-in initramfs case.
+
+```
+$ make sipeed_maix_dock_sdcard_defconfig
+$ make
+```
+
+The build process will generate two files under the output/images directory.
+
+* sdcard.img: The image file for the SD card filesystem. This image has 2
+ partitions. The first partition is a vfat partition containing the kernel
+ uImage and the board device tree binary. The second partition is the root
+ filesystem with busybox installed. The second partition is formatted using
+ ext2 (rev1).
+
+* uboot.bin: U-Boot bootable binary to load and boot the kernel from the SD
+ card.
+
+The SD card can be prepared by writing the sdcard.img file, as follows.
+
+```
+$ sudo dd if=output/images/sdcard.img of=/dev/sdX bs=1M
+$ sync
+$ eject /dev/sdX
+```
+
+Where /dev/sdX is the device file name of the SD card. Once completed, the SD
+card can be inserted into the board and the U-Boot binary image written to the
+board boot flash using the kflash utility.
+
+```
+$ output/host/bin/kflash -b 1500000 -p /dev/ttyUSB0 -t output/images/u-boot.bin
+```
+
+The above command will program U-Boot image to the board boot ROM and open a
+terminal console once the u-boot.bin file is fully programmed. Reboot into the
+newly programmed environment by pressing the board reset button if it does not
+reboot automatically.
+
+The output will be similar to the following.
+
+```

+
+Of note is that the kernel mounts the SD card as read-only by default to avoid
+corruptions of the ext2 root file system when the board is powered down. This
+is recommended as this board does not support clean shutdown or halt.
+
+Similarly to the initramfs build case, a console can be open without
+re-flashing the board using the host tool pyserial-miniterm.

Add two buildroot configuration files to build a minimal Linux
environment for the Sipeed MAIX Bit board. The configurations are:
* sipeed_maix_go_defconfig: Build a bootable kernel image with an
embedded initramfs root file system. The image built can be flashed to
the board as is and does not require a boot loader. This configuration
uses the tiny busybox configuration defined in
board/canaan/k210-soc/busybox-tiny.config.
* sipeed_maix_go_sdcard_defconfig: Build a kernel image with a root
file system on the SD card and using U-Boot as the boot loader. This
uses the default busybox minimal configuration.
Both configurations also enable the kflash and pyserial-miniterm host
tools for flashing image files to the board and opening a terminal
console.
The readme.txt file documents how to build and boot the Sipeed MAIX-Go
board with these configurations.

+Sipeed MAIX-Go Board
+====================
+
+The Sipeed MAXI-Go board is a dual-core RISC-V 64-bits board based on the
+Canaan Kendryte K210 SoC.
+
+Prerequisite
+------------
+
+In order to use the kflash utility to program this board, the user must have
+access to the board USB serial device file. The simplest way to do this is to
+add your user to the same group as this device file. Assume the device file is
+/dev/ttyUSB0, first identify the device group name. In most cases, it is
+either "dialout" or "uucp". Also verify that read-write access is enabled for
+the group:
+
+```
+$ ls -l /dev/ttyUSB0
+crw-rw---- 1 root dialout 188, 0 May 26 13:48 /dev/ttyUSB0
+```
+
+Then add yourself to that group (dialout in this example):
+
+```
+$ sudo usermod -a -G dialout $(whoami)
+```
+
+To enable the above, it is sometimes necessary to logout and login again.
+
+Buildroot Configuration
+-----------------------
+
+Two buildroot configuration files are provided:
+
+(1) Direct Linux Kernel Boot
+
+This is defined by the sipeed_maix_go_defconfig configuration. This
+configuration allows building a bootable kernel image with a built-in initramfs
+root file system (the board SD card is not used). The built kernel image can be
+flashed directly to the board ROM for direct booting. No boot loader is
+required.
+
+(2) U-Boot SD-Card Boot
+
+The sipeed_maix_go_sdcard_defconfig configuration allows building a kernel
+image with the root file system on the board SD card. U-Boot is used as the
+boot loader.
+
+Note: U-Boot does not natively support the Sipeed MAIX-Go board. However, the
+board and device tree differences with the Sipeed MAIX-bit board are small
+enough for U-Boot to work.
+
+Both configuration files will also compile and install the kflash and
+pyserial-miniterm host utilities to program bootable image files to the board
+and open a serial terminal console.
+
+Direct Linux Kernel Boot
+-------------------------
+
+Using the sipeed_maix_go_defconfig configuration, the bootable kernel binary
+image is built as follows.
+
+```
+$ make sipeed_maix_go_defconfig
+$ make
+```
+
+The bootable binary image is the output/images/loader.bin file. This image file
+can be written to the board boot flash using the kflash utility.
+
+```
+$ output/host/bin/kflash -b 1500000 -p /dev/ttyUSB0 -t output/images/loader.bin
+```
+
+Once the kernel image file is fully programmed, a terminal console is open and
+the board can be rebooted by pressing the reset button on the board (if it does
+not reboot automatically).
+
+The output will be similar to the following.
+

+```
+
+To open a terminal console without re-flashing the board, the pyserial-miniterm
+host tool can be used.
+
+```
+$ output/host/bin/pyserial-miniterm --raw --eol=LF /dev/ttyUSB0 115200
+```
+
+The options "--raw" and "--eol=LF" are added here to avoid a double carriage
+return each time a command is entered.
+
+
+U-Boot SD-Card Boot
+-------------------
+
+The build procedure is similar to the built-in initramfs case.
+
+```
+$ make sipeed_maix_go_sdcard_defconfig
+$ make
+```
+
+The build process will generate two files under the output/images directory.
+
+* sdcard.img: The image file for the SD card filesystem. This image has 2
+ partitions. The first partition is a vfat partition containing the kernel
+ uImage and the board device tree binary. The second partition is the root
+ filesystem with busybox installed. The second partition is formatted using
+ ext2 (rev1).
+
+* uboot.bin: U-Boot bootable binary to load and boot the kernel from the SD
+ card.
+
+The SD card can be prepared by writing the sdcard.img file, as follows.
+
+```
+$ sudo dd if=output/images/sdcard.img of=/dev/sdX bs=1M
+$ sync
+$ eject /dev/sdX
+```
+
+Where /dev/sdX is the device file name of the SD card. Once completed, the SD
+card can be inserted into the board and the U-Boot binary image written to the
+board boot flash using the kflash utility.
+
+```
+$ output/host/bin/kflash -b 1500000 -p /dev/ttyUSB0 -t output/images/u-boot.bin
+```
+
+The above command will program U-Boot image to the board boot ROM and open a
+terminal console once the u-boot.bin file is fully programmed. Reboot into the
+newly programmed environment by pressing the board reset button.
+
+The output will be similar to the following.
+
+```

+
+Of note is that the kernel mounts the SD card as read-only by default to avoid
+corruptions of the ext2 root file system when the board is powered down. This
+is recommended as this board does not support clean shutdown or halt.
+
+Similarly to the initramfs build case, a console can be open without
+re-flashing the board using the host tool pyserial-miniterm.

Add a buildroot configuration file to build a minimal Linux environment
for the Sipeed MAIX Bit board.
The configuration file is canaan_kd233_defconfig. It builds a bootable
kernel image with an embedded initramfs root file system. The image
built can be flashed to the board as is and does not require a boot
loader. This configuration uses the tiny busybox configuration defined
in board/canaan/k210-soc/busybox-tiny.config.
U-Boot currently does not support this board, making it impossible to
boot the kernel after loading it from the SD card. However, the SD card
is usable from Linux once booted using the canaan_kd233_defconfig
configuration.
The configuration also enable the kflash and pyserial-miniterm host
tools for flashing image files to the board and opening a terminal
console.
The readme.txt file documents how to build and boot the Canaan KD233
board with this configuration.

+Canaan KD233 Board
+==================
+
+The Canaan KD233 is a dual-core RISC-V 64-bits board based on the Canaan
+Kendryte K210 SoC.
+
+Prerequisite
+------------
+
+In order to use the kflash utility to program this board, the user must have
+access to the board USB serial device file. The simplest way to do this is to
+add your user to the same group as this device file. Assume the device file is
+/dev/ttyUSB0, first identify the device group name. In most cases, it is
+either "dialout" or "uucp". Also verify that read-write access is enabled for
+the group:
+
+```
+$ ls -l /dev/ttyUSB0
+crw-rw---- 1 root dialout 188, 0 May 26 13:48 /dev/ttyUSB0
+```
+
+Then add yourself to that group (dialout in this example):
+
+```
+$ sudo usermod -a -G dialout $(whoami)
+```
+
+To enable the above, it is sometimes necessary to logout and login again.
+
+Buildroot Configuration
+-----------------------
+
+Unlike other K210 based boards (Sipeed boards), U-Boot does not work on the
+KD233 board due to the different wiring for the SD-Card mmc controller. As such,
+the KD233 board can only be used by directly booting into Linux Kernel.
+
+buildroot can be configured to do so using the canaan_kd233_defconfig
+configuration file. This configuration allows building a bootable kernel image
+with a built-in initramfs root file system (the board SD card is not used). The
+built kernel image can be flashed directly to the board ROM for direct booting.
+No boot loader is required.
+
+Once booted, the on-board SD card can be used by Linux.
+
+The configuration file will also compile and install the kflash and
+pyserial-miniterm host utilities to program bootable image files to the board
+and open a serial terminal console.
+
+Direct Linux Kernel Boot
+-------------------------
+
+Using the canaan_kd233_defconfig configuration, the bootable kernel binary image
+is built as follows.
+
+```
+$ make canaan_kd233_defconfig
+$ make
+```
+
+The bootable binary image is the output/images/loader.bin file. This image file
+can be written to the board boot flash using the kflash utility.
+
+```
+$ output/host/bin/kflash -b 1500000 -p /dev/ttyUSB0 -t output/images/loader.bin
+```
+
+Once the kernel image file is fully programmed, a terminal console is open and
+the board can be rebooted by pressing the reset button on the board (if it does
+not reboot automatically).
+
+The output will be similar to the following.

Yes, I've handled other Buildroot patches/topics. Your patches are
lined up in patchwork, and not forgotten. For the record, we have ~300

Thanks a lot!
